Spiral Fuse: melt on the cover with a blown fuse indicators, once the melt blown, the indicator pops up immediately, you can bore through the glass ceramic cap observed, it is often used in machine tools, electrical control equipment. Screw type fuse. Breaking current is large, the voltage level can be used for 500V and below, current levels following circuit 200A Weihai high voltage fuses for short circuit protection. Resettable fuse: using metallic sodium as a melt fuse, having high electrical conductivity at room temperature. When the circuit is short-circuit fault, short-circuit current rapid vaporization temperature sodium Jinan high-voltage fuse, sodium vapor high impedance, thereby limiting the short circuit current. When the short circuit current is removed, the temperature drop, sodium metal to restore the original good conductive properties. Resettable fuse can limit the short circuit current, not really breaking the circuit. The advantage is that the melt need not be replaced and can be reused. Suqian high voltage fuses, fuse, power is supplied by the Xi'an Huayi Huayi power plant. Xian Huayi power plant (www.xahy.com) strong, credible, in Xi'an high-voltage circuit breakers and other industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Huayi power and you hand into the brilliant, for a better future!
